+### CL-040: TASK22260 next slice — reference-data direct service endpointClient adoption
+
+date: 2026-03-25
+author: Cline
+scope: `actions/services/referenceDataDirectService.js`, `actions/clients/README.md`
+type: change
+rationale: Continue the incremental façade/client adoption stream by migrating another bounded direct-service module to shared endpoint request helpers.
+impact: Reduces axios boilerplate and centralizes JSON extraction behavior for reference-data requests without changing public call signatures.
+status: completed
+
+Summary:
+
+- Migrated `actions/services/referenceDataDirectService.js` from direct `axios.get(...).then(res => res.data)` patterns to shared `getJson(...)` helper from `actions/clients/endpointClient`.
+- Preserved existing error behavior:
+    - `logAndReturnEmptyValueErrorResponse` for appeals/project/LPA fetches
+    - `consoleLogger` catch handling for form/mandatory/picklist/notice fetches
+- Updated `actions/clients/README.md` usage notes to include reference-data service reuse.
+
+Validation:
+
+- `npm run lint` -> warnings only (pre-existing `react-hooks/exhaustive-deps`; no new lint errors)
+
+Follow-ups:
+
+- Next optional bounded slice: adopt `getJson`/`requestJson` for selected low-risk read paths in `searchDirectService` or `caseDirectService` while preserving per-function error semantics.
